Sex, bondage, and butterflies: two women explore the extremes of carnal desire in this kinky, deliciously twisted tale of erotic obsession. In a crumbling European estate, butterfly researcher Cynthia (Sidse Babett Knudsen) and her lover Evelyn (Chiara D'Anna) repeatedly enact a sadomasochistic role-playing game, with Cynthia as the stern mistress and Evelyn her subservient sex slave. But as the lines between fantasy and reality begin to blur, and Cynthia grows increasingly uneasy with Evelyn’s insatiable appetite for punishment, their relationship is pushed to the limit. Dripping with dreamlike imagery, Gothic atmosphere, and a lush chamber pop score by Cat’s Eyes, this critically-acclaimed, darkly comic erotic fantasia is a seductive feast for the senses.
